Thanks in advance for any help provided. I am absolutely pulling my hair out over this.
I will start with my set up:
Scientific Atlanta Cable modem (2200 M/N?) ---> Linksys SPA-2102 VOIP ---> Netgear 3500L Wireless Router (Stock firmware, unable to upgrade to DD-WRT). This is also my preferred set up as I want to keep the VIOP in front of the router.
The router is given a static IP address by the VOIP unit of 172.16.0.2
Upon power cycling the router, I am able to access the administration page at 192.168.1.1 or routerlogin.net. After a period of 10 - 30 minutes, I receive a limited or no connectivity pop up on XP. I am still able to access the internet without a problem, however I cannot access the routers administration page until I power cycle.
During the 10 - 30 minute period all of my IP addresses assigned my the router show up as 192.168.1.XXX, after the limited or no connectivity message the addresses are changed to 172.16.0.XXX. This really plays games with my port forwarding that is set up. I am still unable to access the routers administration page. I have had luck once in awhile accessing it at 172.16.0.2.
I do get a warning on the routers administration page after a reset that the IP address of the router has been changed to 192.168.1.1 to avoid a conflict.
I have reset all settings of the VOIP and router to factory many times and still I have no luck.
Thanks for taking the time to read this long post, but I wanted to provide as much information as possible.
